Archon 🐛 [Bug]: Knowledge Base items cannot be displayed after several pdf uploads

Archon Version

v0.1.0

Bug Severity

🟡 Medium - Affects functionality

Bug Description

I have injected 10 pdf in the Knowledge Base but now I cannot get them to be displayed on screen and I get the pop-up: "Failed to load knowledge items". Until 8 pdf it was OK at the 9th, I had to reload the page a few times before being able to display the items, at the 10th, despite multiple reloads, restarts of the stack, I can't get anything displayed.

I see them in Supabase, the calls from the back-end (Archon-Server container) to Supabase are successful (status 200). There is nothing remarkable in the logs of the front-end container but I retrieved error logs from the browser.

System Info

Platform: Linux x86_64
URL: http://localhost:3737/settings
Timestamp: 2025-08-17T03:39:00.802Z
Memory: 37MB used

Steps to Reproduce

Upload several pdf, 1 by 1 one, at least 10 pdf
Try to display the items in the Knowledge Base page

Expected Behavior

I should be able to display all the items uploaded

Actual Behavior

Knowledge base items are not displayed

Affected Component

🔍 Knowledge Base / RAG

Browser & OS

Brave v1.81.135 based on Chromium: 139.0.7258.127

Additional Context

Due to geo-IP restriction I have to use a VPN to reach OpenAI. It does not affect Supabase.

I just tested with 11 PDF documents and I could not replicate the error at the moment:

Are the PDFs you are using by any chance something public and you can provide? Maybe it has to do with them especially.

Also can you try normal Chrome Browser, just in case.

Aug 17 '25 19:08 leex279

Same result with Chromium:

The PDF are e-books about Golang generated with Calibre. I face the same problem with other e-books in PDF generated with Calibre. Also, despite being technical documents with code examples, almost all of them are considered as "Business documents" (I saw another bug about that).

I could share a stack of e-books but not publicly here. I am a Dynamous member so I could share there.

I will retest several things to try to find a pattern.

@SP-937-215 Thanks for the details. Sure share it with me in the Dynamous Community - Private Chat. This would help a lot :)

Feel free to share it with the team internally in Slack!

This should be resolved now, tested on main.

Let me know if you still have issues
